How to mute all sound nowSupport

Before I started using a drawing security pattern to bring my droid out of unlock mode I had the little green unlock circle on the left side and a speaker circle on the right side. The speaker circle would mute all sound and turn off the speaker on my droid. Now that I am using the security pattern I do not have that option anymore.

When you use the power button or the volume controls, does this mute ALL (text, email, etc.) sounds, or just the ringer? I wanted a way to mute all sound quickly say if I am in a movie or a meeting, and when I get out, it is restored back to the original settings. I am using timeriffic, which changes global settings based on a schedule, but also need something for just one time events and restore back.
